Investigation of the behavior of diagonally cracked full-scale CRC deck-girders injected with epoxy resin and subjected to axial tension

Creator:: Smith, Matthew T. (Matthew Todd)
Abstract:: Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...

Shear repair methods for conventionally reinforced concrete girders and deep beams

Creator:: Howell, Daniel A.
Abstract:: Many conventionally reinforced concrete deck girder bridges (RCDG) and their intermediate supporting bent caps were designed during the Eisenhower interstate era of the 1950’s with the AASHO design equations at the time, which subsequently place higher demand on the concrete. The referenced components may exhibit diagonal cracking due to the...

Nonlinear finite element analysis of reinforced concrete structures strengthened with FRP laminates

Creator:: Chansawat, Kasidit
Abstract:: The Horsetail Creek (HC) bridge is an example of an Oregon bridge that was classified as structurally deficient and was not designed to withstand earthquake (EQ) excitations. A fiber-reinforced polymer (FRP) rehabilitation was performed on the HC bridge to increase flexural and shear capacities for traffic loads. However, a seismic...

Design, analysis and evaluation of bridge superstructures for live loads

Creator:: Turan, O. Tugrul
Abstract:: Due to age, original design that is deficient by modern standards, inadequate maintenance, environmental conditions, and increasing loads, large numbers of bridges in United States and elsewhere are classified as deficient and in need of rehabilitation or replacement. According to a national bridge inventory established by the Federal Highway Administration,...

Effect of constituent materials and curing methods on the abrasion resistance and durability of high performance concrete for pre-cast pre-stressed bridge deck slabs

Creator:: Keshari, Shweta
Abstract:: This thesis is the consequence of a research effort undertaken by the School of Civil and Construction Engineering at Oregon State University and funded by the Oregon Department of Transportation (ODOT) and the Federal Highway Administration (FHWA). The principal objective of the effort was to reduce the life cycle cost...

Design and fatigue behavior of near-surface mounted CFRP bars for shear strengthening of RC bridge girders

Creator:: Johnson, Brandon Ang
Abstract:: Carbon fiber reinforced polymer (CFRP) materials are emerging as an effective means of strengthening and rehabilitating bridges. Near surface mounting (NSM) is a newer technique for application of CFRP for retrofitting of bridge members that provides advantages over conventional strengthening techniques. The technique is still new and uncertainties remain regarding...

High-cycle fatigue response of diagonally-cracked conventionally reinforced concrete bridge girders

Creator:: Lee, Ae-young S.
Abstract:: The behavior of stirrups engaged by diagonal cracks and under service loads is largely unknown. Full-size laboratory specimens were loaded to induce diagonal cracks and subjected to high-cycle fatigue loading to represent a service life of 50 years. Tests indicated little change in the average stirrup stress range and mean...

Investigation of the fatigue behavior of diagonally-cracked CRC deck-girders repaired with CFRP

Creator:: Williams, Grahme T.
Abstract:: Fiber reinforced polymers (FRP) are becoming more widely used for repair and strengthening of conventionally reinforced concrete (CRC) bridge members. Once installed, the repair may be exposed to millions of load cycles during service life. The anticipated life of FRP repairs for shear strengthening of bridge members under repeated service...

Reliability based bridge assessment using modified compression field theory and Oregon specific truck loading

Creator:: Daniels, Theresa Kathryn
Abstract:: Assessment of an existing bridge is needed when the structure exhibits signs of distress. Assessment practices require refinement in the calculation of loading and resistance while maintaining an acceptable level of risk, to minimize costs associated with repair, replacement and weight restrictions. Previous risk-based assessments evaluated the strength cases for...
